The passive road sensor IRS31Pro-UMB is flush-mounted in the road. The two part housing design allows the combined sensor/electronics unit to be removed for maintenance or calibration at any time. The following variables are recorded: Road surface temperature, water film height up to 4 mm, freezing temperature for different de-icing materials (NaCl, MgCl, CaCl), road condition (dry/damp/wet/ice or snow, damp with salt, wet with salt), friction (Grip), ice percentage. Optional: 2 additional depth temperatures, e.g. at 5 cm and 30 cm. The measurement data is available for further processing in the form of a standard protocol (Lufft UMB protocol).
Features
- Freezing temperature output already from pre-set dry-damp threshold (e.g. 10µm according to new TLS specification).
- Replaceable sensor electronics (for easy calibration or maintenance)
- Polling via RS485 interface
- Low energy consumption (solar operation)
- Radar principle to measure water film
- Analogue outputs in combination with a converter (DACON – 8160.UDAC)
